I recently saw a Hank Green video (https://youtu.be/DpGU8NARX-s?t=558) where he gives a definition of pseudoscience that I thought was pretty good.
The basic idea is that science is the process by which we create evidence for something, and then have that evidence be challenged. Doing this repeatedly helps us notice that some structures are pretty good for creating good evidence (ie statistics, double blind trials, falsifiability, etc.). Pseudoscience is using these same structures to make what you’re doing look like science, without actually interacting with the “being challenged” part.
I think the parent meant an ideal form of price discrimination where the entire consumer surplus is instead claimed by the company.
